摘　　要：在 PC微机的总线上接两片 Intel 82 5 3芯片 ,采用软硬件结合的方式 ,实现对宽频带、连续变化的频率进行高精度实时跟踪测量 .该方法用可编程计数器芯片实现测频 。This paper presents a method with which high precision and real time tracing measurement can be implements on broad band and continuous varying frequency. Such a method adopts a technique of extending two Intel 8253 chips to PC bus and by means of combining software with hardware. This method can also be applied to other series of microcomputers for detecting frequency by virtue of programmable counter chip.
